Adjustable fixture for torsion shaft of wind turbine above 3 megawatt

Abstract

The invention relates to an adjustable fixture for a torsion shaft of a wind turbine above 3 megawatts. The adjustable fixture comprises a fixture main body and a supporting plate in perpendicular to the fixture main body. A clamping mouth for placing containing a workpiece is arranged at the top end of the supporting plate. Hexagonal socket bolts for aligning the workpiece are arranged at the clamping mouth. Slots are arranged in the fixture main body. Bolts tightly fix the fixture on a worktable through the slots. Bolt holes are additionally arranged in the fixture main body. A pressing plate tightly presses the workpiece through the bolt holes. Rib plates which take an effect of reinforcing and supporting the supporting plate are additionally arranged on the fixture. By using the adjustable fixture, not only can the problem that clamping and alignment are required to be conducted for many times during punching of a center hole of the torsion shaft of the wind turbine because of the short worktable of a digital display boring machine be solved, can once-for-all clamping for machining be realized and can the production efficiency be improved, but also the dimensional accuracy and the position tolerance are better guaranteed.

Description

Technical field [0001] The invention relates to the processing of a torsion shaft of a wind power product fan, in particular to an adjustable clamp used when the fan torsion shaft punches a center hole. Background technique [0002] With the increasing depletion of traditional energy sources and the increasing environmental pollution, wind energy as a green energy source has received more and more attention. In order to better develop and develop wind power products, the state has given many favorable policies to encourage companies to move closer to the wind power industry, produce energy-saving and environmentally friendly products, and further develop new industries while revitalizing and promoting national industries. The state's efforts to encourage the development of new energy have been continuously strengthened, prompting an endless stream of various energy products.

Problems solved by technology

[0003] The fan torsion shaft is an important part of wind power products. During the machining process of the center hole of the fan torsion shaft, due to the short worktable of the digital display boring, multiple clamping and alignment are required during the center hole drilling process. Loading and unloading workpieces is very troublesome, and the versatility is poor, and one-time processing cannot be completed, which greatly reduces the efficiency of manufacturing
